I think Aiken goes first, then Rondon, so Kolek to the Sox...which works for me.

Watching the MLB Network preview show, they had Kolek as their #2 guy, behind Aiken only.
They see this as a 3 man draft, in the top tier, so the Sox might have won last season by losing just more than the Cubs.

Altho Kolek seems to throw across his body a bit, and does remind a bit of Kerry Wood, but with a much stronger frame/body.
